I don't see the problem. You are passing a pointer to the info
structure and of course you can change it's contents later and the
timer_func will get the current value when it accesses info->timer_id.
Apart from that, I don't think you need the timer_id since you can
remove the timeout by returning FALSE from timer_func.


Salut, Sven
